Highly sensitive olfactory biosensors for the detection of volatile organic compounds by surface plasmon resonance imaging
2018
International audience; Nowadays, monitoring of volatile organic compounds (VOCs) is very important in various domains. In this work, we aimed to develop sensitive olfactory biosensors using odorant binding proteins (OBPs) as sensing materials. Three rat OBP3 derivatives with customized binding properties were designed and immobilized on the same chip for the detection of VOCs in solution by surface plasmon resonance imaging (SPRi). We demonstrated that the proteins kept their binding properties after the immobilization under optimized conditions. The obtained olfactory biosensors exhibited very low limits of detection in both concentration (200pM of beta-ionone) and in molecular weight of …
Characterization of the "viable but nonculturable" (VBNC) state in the wine spoilage yeast Brettanomyces.
2012
Although the viable but not culturable (VBNC) state has been studied in detail in bacteria, it has been suggested that maintenance of viability with loss of culturability also exists in eukaryotic cells, such as in the wine spoilage yeast Brettanomyces. To provide conclusive evidence for the existence of a VBNC state in this yeast, we investigated its capacity to become viable and nonculturable after sulfite stress, and its ability to recover culturability after stressor removal. Sulfite addition induced loss of culturability but maintenance of viability. Increasing the medium pH to decrease the concentration of toxic SO(2) allowed yeast cells to become culturable again, thus demonstrating …
Anticipatory Postural Adjustments and kinematic arm features when postural stability is manipulated
2018
International audience; Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements, The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulate…
Communicating across the borders: managing work-life boundaries through communication in various domains
2021
Communicating work issues at home and home issues at work, also known as across-the-border (ATB) communication, is a part of everyday work and family interaction. This study focuses on the concept of ATB communication, using Work/Family Border Theory, according to which the boundaries between work and private life are seen as negotiated and shaped through social interactions and practices. We argue that through ATB communication, and especially by focusing on what is shared and how, employees can manage boundaries and achieve work-life balance. Altogether, 32 informants, comprising journalists (N = 16) and their relational others (N = 16), were interviewed to investigate the role of ATB com…

Pleasure or health: Do children have to choose?
2017
International audience; Pleasure from eating is known to be a strong predictor of children’s food choices. Yet, children’s food preferences generally do not align with dietary recommendations, children rate energy-dense foods as the most liked and vegetables the least liked. In order to incite children to adopt a healthy diet, parents, caregivers, and national campaigns put forward nutritional arguments. However, there is limited research regarding the impact of the level of nutritional concern on children’s food choices, especially compared to pleasure-oriented goals. This talk is an overview of the research work I have conducted during my PhD, and explores the relationships between childr…
A web-based and mobile intervention with brochure support providing complementary feeding guidelines to first-time parents in France: Randomized Cont…
2023
Purpose: In light of the latest epidemiological and nutritional knowledge and scientific evidence supporting responsive feeding, the French feeding guidelines for 0-3 years were recently updated and nationally disseminated through a brochure and media campaign by Santé publique France. Moreover, smartphone apps become increasingly popular and is likely relevant to provide timely information across development to inform parents about child feeding practices but their effect is seldom evaluated. This randomized controlled trial (RCT) aims to investigate whether the provision of guidelines through an app and a brochure (vs. brochure alone, usual service) results in healthier parental feeding p…
Gli strumenti di conciliazione nella prassi: analisi su un campione di contratti collettivi aziendali
2020
Individuare le vie verso un efficiente sistema di work-life balance è questione complessa e impone di considerare molteplici fattori, tra cui il ruolo strategico che può assumere la contrattazione collettiva nell’integrazione delle misure adottate a livello normativo, perfezionando la disciplina con diritti mirati o per meglio garantire l’attuazione di quelli esistenti. Fino a che punto, però, i contratti collettivi raggiungano nei fatti l’ambizioso obiettivo di potenziare i risultati in questa direzione è ciò che si intende meglio indagare, pur senza pretesa di esaustività. Il presente contributo si concentra sull’analisi dei contenuti di un campione di contratti collettivi di secondo live…
Living in the blurry zone : a study of the wellbeing and work-life balance of Finnish SME entrepreneurs
2018
Pienten ja keskisuurten yritysten yrittäjät ovat tärkeä osa Suomen taloutta. Tämän vuoksi heidän hyvinvointiaan sekä työn ja muun elämän tasapainoa on tärkeää tutkia. Liiketoiminta kirjallisuus on perinteisesti tukenut näkemystä, jonka mukaan yrityksen johtaja tukee työntekijöidensä työn ja muun elämän tasapainoa sekä hyvinvointia. Tämä näkemys ei kuitenkaan ota huomioon yrittäjiä, jotka toimivat yrityksiensä johtajina. Entä heidän hyvinvointinsa? Mikä on heidän työn ja muun elämän tasapainon tila? Tämä tutkimus pyrkii vastaamaan muun muassa näihin kysymyksiin. Tutkimukseen osallistui kaksitoista pienten ja keskisuurten yritysten yrittäjää. Nämä yrittäjät toimivat eri toimialoilla ja eri pu…

This paper presents findings of a consumer survey carried out in Vietnam. the survey has been implemeted in two steps : qualitative and quantitative. The main profile of respondants are women, urban consumers, age from 24 - 39, office workers. The results provide an overall view on the criteria of choice in food buying decision. Concretely, sensorial factors like observing, touching, smelling play a very important role in food choice, more than trust on the vendor or certifcation of a third party like the Government. the consumer appreciates fresh food, assimilating to nutritional value, health and quality of the meal. However, there seems to be a generational difference between two generat…
